The force reducing device is divided into a die opening force reducing device and a die closing force reducing device, and at least one die opening force reducing device is arranged between the template 9 and the base 7 and is used for assisting in providing torque required by the opening process of the template 9; at least one mold closing force reducing device is arranged between the mold plate 9 and the base 7 and is used for assisting in providing torque required by the mold plate 9 in the closing process. The force reducing device also comprises a screw rod 1 and a supporting plate 5; one end of the screw rod 1 is hinged to the base 7, a fixing piece is arranged on the screw rod 1 and is an assembly of a nut 2 and a gasket 3, the supporting plate 5 is movably mounted on the screw rod 1, the supporting plate 5 is connected with a mold, at least one elastic damping element is arranged between the fixing piece and the supporting plate 5, and the elastic damping element is in an energy storage state at an initial position of mold opening or mold closing.
The mold opening force reducing device in embodiment 1 and the mold closing force reducing device in embodiment 2 need to be used in combination if both the mold opening force reducing and the mold closing force reducing are required in one mold. That is, the support plate 5 and the mold plate 9 in the mold opening and force reducing device need to be loosened in the mold opening process, and the support plate 5 and the mold plate 9 in the mold opening and force reducing device need to be loosened in the mold closing process, so that the operation is complicated, and the working hours of operators are increased. In order to solve the above inconvenience, embodiment 3 of the present invention realizes the function of combining the mold opening force reducing device and the mold closing force reducing device in one apparatus. As shown in fig. 5, the force reducing device of the present invention includes a screw rod 1, an elastic damping element and a supporting plate 5, wherein one end of the screw rod 1 is hinged to a base 7, two ends of the screw rod 1 are respectively provided with an upper fixing member 2-2 and a lower fixing member 2-1, the supporting plate 5 is movably mounted on the screw rod 1 between the upper fixing member 2-2 and the lower fixing member 2-1, the supporting plate 5 is connected with a template 9 through a fixing plate 6, the lower fixing member 2-1 and the supporting plate 5 are provided with a first elastic damping element, and the upper fixing member 2-2 and the supporting plate 5 are provided with a second elastic damping element. In embodiment 3 the first elastic damping element is a first spring 4-1 and the second elastic damping element is a second spring 4-2. At the initial position of die opening or die closing, the first spring 4-1 or the second spring 4-2 is in an energy storage state.
Example 3 mold opening process:
as shown in fig. 6a, the initial state of the force reducing device is the mold closing state of the mold plate 9, the energy storage state of the second spring 4-2 is the compression state, the first spring 4-1 is in the free state, and x1 in the figure is the gap between one end of the first spring 4-1 and the support plate 5. The center of mass of the template 9 is located on the right side of the first hinge point, as shown in fig. 6b, the template 9 is turned over counterclockwise under the action of the force application lever 8, the center of mass of the template 9 is gradually moved from the right side of the first hinge point to the left side of the first hinge point in the process of turning over the template 9 counterclockwise, and the force reducing device provides an auxiliary torque mainly in the process that the center of mass of the template 9 is gradually moved on the right side of the first hinge point in the process of opening the mold, specifically as follows: the screw 1 is turned counterclockwise by the support plate 5 during the process that the center of mass of the mold plate 9 is gradually moved at the right side of the first hinge point, that is, the process that the mold plate 9 is turned counterclockwise. The support plate 5 moves downwards during the overturning process of the screw rod 1, so that the distance between the upper fixing part 2-2 and the support plate 5 is increased, and the second spring 4-2 is gradually restored to the free state from the compressed state, and the moment formed by the elastic force released by the second spring 4-2 in the process is the same as the moment applied by the force application lever 8, namely, the second spring 4-2 provides partial moment in the mold opening process. When the center of mass of the template 9 is located at the right side of the first hinge point, the turning can be realized by means of the self weight of the template 9. The moment generated by the self weight of the template 9 can cause the template 9 to overturn in an accelerated way, at the moment, the support plate 5 continues to move downwards to start compressing the first spring 4-1, at the moment, the second spring 4-2 can be still in a compressed state or the second spring 4-2 can be in a free state, and the compression of the first spring 4-1 generates resistance to slow down the overturning speed of the template 9. When the mold is turned to the right position as shown in fig. 6b, the first spring 4-1 is in the energy storage state, i.e. in the compression state, the second spring 4-2 is in the free state, and x2 in the figure is the gap between one end of the second spring 4-2 and the support plate 5.
Example 3 mold closing process:
as shown in fig. 6b, the initial state of the force reducing device is that the template 9 is in an open state, the first spring 4-1 is in an energy storage state, namely in a compressed state, the second spring 4-2 is in a free state, and x2 in the figure is a gap between one end of the second spring 4-2 and the support plate 5. The center of mass of the template 9 is located on the left side of the first hinge point, as shown in fig. 6a, the template 9 is turned counterclockwise under the action of the force application lever 8, the center of mass of the template 9 is gradually moved from the left side of the first hinge point to the right side of the first hinge point in the process of turning the template 9 clockwise, and the mold closing force reducing device mainly provides an auxiliary torque in the process that the center of mass of the template 9 is gradually moved on the left side of the first hinge point, as follows: the screw 1 is turned clockwise by the support plate 5 during the progressive movement of the center of mass of the die plate 9 at the left side of the first hinge point, i.e., the clockwise turning of the die plate 9. The supporting plate 5 moves upwards during the overturning process of the screw rod 1, so that the distance between the lower fixing part 2-1 and the supporting plate 5 is increased, and the first spring 4-1 is gradually restored to the free state from the compressed state, and the moment formed by the elastic force released by the first spring 4-1 in the process is the same as the moment applied by the force application lever 8, namely, the first spring 4-1 provides partial moment in the mold opening process. When the center of mass of the template 9 is located at the left side of the first hinge point, the template 9 can be relied on for realizing the mold closing by self-weight. The moment generated by the dead weight of the template 9 can cause the template 9 to accelerate die assembly, at the moment, the supporting plate 5 continues to move upwards and starts to compress the second spring 4-2, at the moment, the first spring 4-1 can still be in a compressed state or can be in a free state, and the second spring 4-2 is compressed to generate resistance to slow down the die assembly speed of the template 9, so that large impact force can be prevented from existing in the die assembly process. When the mold is turned to the right position as shown in fig. 6a, the second spring 4-2 is in the energy storage state, i.e. in the compression state, the first spring 4-1 is in the free state, and x1 in the figure is the gap between one end of the first spring 4-1 and the support plate 5.
The elastic modulus of the first spring 4-1 and the second spring 4-2 in embodiment 3 may be the same, or may be different according to the different buffering in the mold closing and opening processes.
The invention discloses a concrete mould, wherein a template overturning device is arranged on one side of a side mould of the concrete mould.
